Well tbf those are post codes designed by the postal service to represent states. I wouldn’t really count it as a naturally developed abbreviation like the ones above, it’s no different from .fr, .es, .co.uk, etc.
The abbreviations for states used before the two-letter ones, however, are much weirder! E.g. Penna. for Pennsylvania
